Rescuers scan Philippines waters for signs of survivors.
A passenger ferry collided with a cargo ship Friday and sank in minutes outside a central port, killing at least 38 people.
Authorities hoped some of the 82 missing would still be found alive two days later.
But divers were having a difficult time as oil spilling from the sunken ship lowered visibility.
Meanwhile families are waiting on shore for any word of their loved ones.

"I pray that they are still alive, so I can meet them. I don't know what to do if they're dead, but if they are, I hope I can at least find their bodies."
The government ordered an investigation into the cause of the crash and the criminal liabilities of both ships.
